Re: Modelling misshapen Walls
@GCFdesign:
My Point-Cloud Data for the whole Building is 10Million points. I reduced it to 1cm.
I don't have the Software installed right now but i guess if I redownload it, then its the newest.
Do you know PointSense? there you can compute at least the modeling error.
I would really liek to see an example of modeling a misshapened wall !!
@Jamesrye:
I watched the Video and it is very promissing. But is there no option to fit the wall directly on the pointcloud?
Becuase if I use sectioning on before, then i dont know if it will fit properly...
@ All of you:
What is the best software to model pointclouds in general? Revit is good but it is also very very extensive :/...

Archicad? Briscad Bim? Tekla?
I don't know any prices but these come to mind.

Re: Modelling misshapen Walls
Revit does the job.
It is how you wish to model, resolution etc.
I am a structural draughtsman by trade and even with as-built modelling, Revit is fine.
If you can get me even an extract of some of your data, I'll show you.

Re: Modelling misshapen Walls
For modelling non-uniform walls such as a heritage sites from a point cloud you might be better to use a meshing package rather than a BIM package, e.g. Bentley ContextCapture or similar. If software cost is an issue, maybe look at meshlab

Re: Modelling misshapen Walls
The images reflect a wall captured via a laser scanner, then meshed, then that mesh located within Revit.

Re: Modelling misshapen Walls
Loads of ways to deal with this in Rhino, or other software. As a previous poster mentioned, you could mesh the walls in meshlab (or geomagic or 3D reshaper). Import the mesh to Rhino and cut sections - then loft them. Just import the mesh and then type contour, enter 0,0,0 and then 0,0,1 to specify direction then enter countour interval. Then loft the curves.
Alternatively, just reduce the point cloud, export as XYZ and then import that to Rhino and then create sections using "fit curve through points command". Rhino even has a command to compare points to a model "pointdeviation".
Rhino can do nurbs meshing, but only on small point clouds - I think the command is meshpatch or mesh from points (I forget). 3rd party plugins are available. The trouble with Rhino is that the interface is a bit tricky - much better than Blender3D's though!
You can do soooo much in Rhino3D, it is a fantastic and under-rated software. Fit planes through points, cylinders through points etc... Its a great modelling tool - I once modelled a ships hull using Rhino. This video isn't mine, but gave me the principals of how it could be done.

Here are the results relating to data within Revit and a quick render via Lumion...
